Most of these reviews will be subjective. What may be acceptable or good to one person, may not necessarily be so to others.
I would view these as a general guide only, as a part of wider research through other sources, and definitely do my own testing (if possible} prior to purchasing.

Even if you can get it kick started, when it is at that stage, it won't be long before the sdm fails completely.
That is what happened to mine, and I converted it to screw drive.
Focus actually seems a bit faster now, just a bit noisier.

Glad you like my photos Andrew.
If I ever get to Montreal again (quite unlikely at this stage) will try and get in touch with you.
Similarly, if you make your way to Melbourne, send me a PM and I will be glad to touch base and do a photographic tour of the city with you.

I spent 10 days in New York recently on vacation. Ï suggest you get a "New York City Pass" as already suggested by Special K, which gets you to most museums, attractions, lets you use the hop-on-off tourist bus, includes a boat tour as well. I found it great value. That is providing you stay in Manhattan.
For architecture photography in the city you will definitely want a wide lens. I found the 12-24 to be great.

I have taken approx. 3000 shots on my K5IIs since I got it, and only noticed moire on about dozen shots.
Actually, I had to look hard to find it. Obviously, it depends on type of subjects one photographs.
